A teaser bull is a term describing a bull whose reproductive system has been surgically altered to render him sterile. The purpose of such bulls is to aid in detection of cows in estrus to facilitate when to artificially inseminate. The bull is sterilized by either vasectomy or caudal epididymectomy. In addition to sterilization, other surgical options are described that prevent intromission and the spread of venereal disease. This article describes briefly some of those options. The procedures described are those preferred by the authors and can be performed in the field. Some of the pros and cons of these procedures are discussed.
